Fading Windows and Minimize Effect are the only Window Animations that some with Compiz. All of the other animations belong to Compiz-Fusion.

Fading Windows is a nice basic window animation that uses a fade effect to transition windows between various states of opening, minimizing, unminimizing, focusing and unfocusing. It gives the user configuration control over how fast the window will fade on initiating as well as which windows will be effected by the animation.
